Abstract (en)
The present application relates a method for key management in a field-programmable integrated part (42) of an integrated circuit (40). According to the method, a hardware configuration (51) for the field-programmable integrated part (42) is loaded into the field-programmable integrated part (42). The hardware configuration (51) includes a key derivation functionality (45). Further, using the key derivation functionality (45), a cryptographic key is derived based on information provided in the field-programmable integrated part (42).
